The present Web surroundings is mostly composed of HTML(Hypertext Mark-up Language) and thereby users obtain web informations mainly in GUI(Graphical User Interface) environment by clicking mouse in order to keep up with hyperlinked informations. However it is very inconvenient to work in this environment comparing with easily accessed one in which human`s voice is utilized for obtaining informations. Using VoiceXML, resulted from XML, for supplying the information through telephone on the basis of the contemporary matured technology of voice recognition/synthesis to work out the inconvenience problem, this paper presents the research results about VoiceXML VUI(Voice User Interface) Browser designed and implemented for realizing its technology and also the VoiceXML Dialog designed for the purpose of the browser's efficient use.

This paper is addressed to a design and implementation of Korean voice web browser using voice technologies for controling web browser and selecting contents in the web document, and converting them to voice after HTML analysis. Main feature of this web browser is universal design which considers both of normal person and visual disabled, allows multi-modal interface. As voice interface for visual disabled, it supports tree structure which allows to recognize web document structure easily by only voice guidance regardless of frame usage, can handle all elements described as tag in the web document, identify them as predefined different voice property according to element property. This method gets rid of additional guidance voice for element property without audio style sheet or additional programming effort.

The web has become indispensable in all of our daily lives. We communicate, study and get information with others through the web. This behavior also continues in the smart phone environment. The biggest problem is that the small display screen of a smart phone degrades the accuracy in selecting or manipulating content for people with low vision. To compensate for this, voice guidance services that combine touch and voice, such as VoiceOver and Talkback, are currently provided to smart phone devices. However, restrictions arise in GUI, TTS control problems, and content expansion and selection. In addition, unnecessary content is also output by voice, which causes fatigue for low vision people to use. In this study, we propose a mobile web browser interface that selects and enlarges a desired area from web browsers and contents, or outputs it as a voice so that people with low vision can easily use the mobile web browser. In this paper, we propose a context selective focusing function that enables selection for each element of web content. In addition, we intend to develop a mobile voice web browser that can enlarge the selected content or output it by voice.

In this paper, we describe a Voice Command Web Browser using a variable vocabulary word recognizer that can do Internet surfing with Korean speech recognition on the Web. The feature of this browser is that it can handle the links and menus of the web browser by speech. Therefore, we can use speech interface together with mouse for web browsing. To recognize the recognition candidates dynamically changing according to Web pages, we use the variable vocabulary word recognizer. The recognizer was trained using POW (Phonetically Optimized Words) 3,848 words. So that it can recognize new words which did not exist in training data. The preliminary test results showed that the performance of speaker-independent and vocabulary-independent recognition is 93.8% for 32 Korean words. The Voice Command Web Browser was developed on windows 95/NT using Netscape Navigator and reflected usability test results in order to offer easy interface to users unfamiliar with speech interface. In on-line experiment of speaker-independent and environment-independent situation, Voice Command Web Browser showed recognition accuracy of 90%.

음성인터페이스 관련 표준화는 음성 대화, 음성인식/합성, 전화망 등의 접속망을 상호 분리하여 음성정보시스템 구성요소들 각각의 상호 독립적인 개발을 보장해 주며, 각 요소의 이해가 없이도 음성정보시스템을 개발할 수 있도록 함으로써 음성정보기술의 보급 및 확산에 크게 기여하고 있다. 이에 W3C에서는 Voice Browser에 대한 표준화를 현재 진행 중에 있으며 Vocie Browser WG에서 Voice Browser를 위한 SIF(Speech Interface Framework)를 제안하였다. 제안된 SIF에서 Voice Browser가 음성인식을 실행하기 위해서는 많은 자원의 소요와 부하가 생길 수 있다. 이러한 문제점을 해결하기 위해 본 논문에서는 음성인식 웹 서비스를 기존의 SIF에 추가한 새로운 형태의 SIF를 제안하고자 한다. 음성인식은 원격 시스템에서 수행하고 그 결과를 Voice Browser가 사용할 수 있도록 음성인식 웹서비스 환경을 구축하였다. 그리고, XML-SRGS 포멧의 grammar를 음성인식기가 사용하는 EBNF 포멧의 grammar로 변환시키는 변환기를 구현하였다.

As a voice browser is introduced, voice dialog application becomes available on the Web environment. The voice dialog application consists of voice Web pages that need to translate the dialog scripts into SALT(Speech Application Language Tags). The current Web pages have been designed for visual. They, however, are potentially capable of using voice dialog. This paper, therefore, proposes an automated voice Web generation method that finds the elements for voice dialog from Web pages based HTML and converts them into SALT. The automatic generation system of a voice Web page consists of a lexical analyzer and a syntactic analyzer that converts a Web page which is described in HTML to voice Web page which is described in HTML+SALT. The converted voice Web page is designed to be able to handle not only the current mouse and keyboard input but also voice dialog.

인터넷 붐을 타고 현재 WWW은 수많은 자료를 인터넷상에 축적했다. 단순히 www의 페이지만을 따져도 수 많은 페이지를 가지고 있고, 이제는 Gopher, Ftp, News group 또한 WWW 인터페이스를 통해 엑세스가 가능하다. 이러한 수많은 자료가 웹상에서 링크로 연결되어 있다. 자료가 늘어날수록 이러한 링크 또한 늘어난다. 이런 환경에서 전통적인 입력 장치인 마우스와 키보드와 더불어 Voice를 통한 Nevigating을 제공함으로써 좀 더 용이한 WWW의 사용을 제공하고자 음성지원 Web Browser를 설계하고자 한다.

In this paper, We have developed the Internet web browser for the blind and visually impaired person. The Internet Web browser system consists of personal computer connected to Internet, braille display, voice synthesis devices for character information, tactile display for the representation of web image and braille printer for web page printing. We convert character in the web page to braille and print it to braille display. The image in the web page is printed with tactile display actuated by solenoid. The blind can acess the Internet web site with this web browser system and understand the Internet information.

The present web informations are mainly described in terms of HTML, which users obtain through input devices such as mouse, keyboard, etc. Thus the existing GUI environment have not supported human's most natural information acquisition means, that is, voice. To solve the problem, several vendors are developing voice user interface. However these products are deficient in man -machine interactivity and their accommodation of existing web environment. This paper presents a VUI(Voice User Interface) supporting web browser by utilizing more and more maturing speech recognition technology and VoiceXML, a markup language derived from XML. It provides users with both interfaces, VUI as well as GUI. In addition, XML Island technology is applied to the bowser in a way that VoiceXML fragments are nested in HTML documents to accommodate the existing web environment. Also for better interactivity, dialogue scenarios for menu, bulletin, and search engine are suggested.
